TEST FACILITY
FULL DIAGNOSTICS AND
FAULT FINDING

OUR ROTATING MACHINE TEST FACILITY HAS BEEN DEVELOPED TO PROVIDE COMPREHENSIVE TESTING FOR LOW- AND MEDIUM-VOLTAGE ELECTRICAL MACHINES, SUPPORTING BOTH DEVELOPMENT AND FACTORY ACCEPTANCE TESTING (FAT).

The facility is designed to accommodate a wide range of machine types, including synchronous, induction, and permanent magnet machines.  With flexible supply configurations, high-power loading capability, and advanced measurement systems, the PPI test bed enables accurate performance evaluation under both sinusoidal and converter-fed conditions. Testing is conducted in alignment with IEC and IEEE standards, ensuring reliable, repeatable, and industry-recognised results.
